I've been a Polk Audio home theater enthusiast for years, having owned several different-sized Polk systems that I've loved. If I was building a new surround sound system today, I'd strongly consider the HTS 12 for my all-important bass production.

This hard-hitting sub can fill even large rooms with deep, responsive bass. My hunch? If you're like me, you may look forward to watching movies with family or friends, just to show them how good the bass sounds.

The Polk Audio HTS 12 powered sub features a sleek, rounded enclosure and a removable grille.

A new design adds visual interest

This sleek sub features a hip, updated design with rounded corners and a slot on the bottom that shows off the flared, down-firing port — a bit of a departure from Polk's previous enclosures. Cosmetically, it's my favorite Polk sub design to date.

But the HTS 12 offers more than just good looks. It pairs a 12", front-firing driver with a 200-watt amp for impactful bass from music and movies. Use it as part of a stereo music system, or as part of a Polk Audio Signature home theater system.

Get the most out of your sub

Where you place your sub within your room makes a big difference in how it sounds. Check out our tips for placement and setup to get the best performance out of your system.

Controls: Built-in controls for variable volume, low pass filter, and
phase let you tune in optimum bass levels. All controls are found on the
rear-panel of the powered sub.

Volume: The rotary volume knob adjusts the volume of the powered
sub relative to the other speakers in the system.

Low-Pass Filter: The variable low-pass filter is adjustable from
40-160 Hz. The low-pass filter is only active for the powered sub's stereo
RCA inputs. The low-pass filter is deactivated when using the powered sub's
LFE input.

Phase: The phase switch allows you to select 0-degrees (normal) or
180-degrees (reverse). If the bass sounds muddy or unclear, toggling the
phase control can sometimes strengthen the bass attack.

LFE Input (Unfiltered): The LFE input consists of an unfiltered
mono-RCA jack (the LFE input bypasses the powered sub's variable low pass
filter). Using the LFE input when connecting to an AV receiver or integrated
amp with a filtered LFE output and built-in crossover control.

Stereo RCA Input (Filtered): The Stereo input consists of a left
& right RCA jack (both jacks are filtered). Use the Stereo input when
connecting to a receiver or integrated amp that does not have an LFE output,
but does provide a preamp output.

Auto & DC Power On/Off: The powered subwoofer will automatically turn on
when an audio signal is received and off when there is no audio signal for about
20 minutes. There is also a 12V trigger input on the back of powered sub which
allows it to power on with your receiver or integrated amp that features a 12V
trigger output (the 12V trigger provides a faster auto on/off).

Note: There is a switch on the back of the powered sub that indicates
which power on/off method you will be using - Auto or DC.

Placement: You may place the powered subwoofer anywhere in
your room, but it will perform best when it's on the same side of the room as
your system's front speakers. Also, placing the subwoofer near a wall or in a
corner will increase its loudness.

Frequency Response: The overall frequency response for the
subwoofer is 22-180Hz, and the -3 dB frequency response is 28-120Hz.
